progress:		(V2TIMDownLoadProgress)	progress
succ:		(V2TIMSucc)	succ
fail:		(V2TIMFail)	fail

Download a video screenshot

The downloadSnapshot API downloads screenshots from the server each time. If cache or storage is required, you can use UUIDs as keys for external storage. The IM SDK does not store resource files.

Parameters

path	Screenshot save path, which must be specified externally

nextElem()

- (V2TIMElem *) nextElem

Get the next Elem. If your message has multiple Elems, you can get the next Elem object from the current Elem. If the return value is nil, it means the Elem acquisition is over. For detailed usage, please refer to the document Message sending and receiving

appendElem:()

- (void) appendElem:

(V2TIMElem *)

elem

Add the next element
To configure multiple elements, you can add the next element via the element of a Message object after creating the Message object. The following is the sample code for creating V2TIMTextElem and V2TIMCustomElem elements:

    V2TIMMessage *msg = [[V2TIMManager sharedInstance] createTextMessage:"text"];
    V2TIMCustomElem *customElem = [[V2TIMCustomElem alloc] init];
    customElem.data = ["自定义消息" dataUsingEncoding:NSUTF8StringEncoding];
    [msg.textElem appendElem:customElem];

Attention

• This API can be called only by elements of a Message object created via createMessage.
• This API can be used to add elements only of the V2TIMTextElem, V2TIMCustomElem, V2TIMFaceElem, and V2TIMLocationElem types.
